What processors do netbooks use? Vaious manufacturers have marketed their netbooks using different processors.

The HP Mininote 2133 for example was powered with a VIA C7-M CPU in various speed configurations.

Quote:
In early April 2008 the schoolroom-use oriented, ultra-portable HP 2133 Mini-Note PC family debuted with an entirely VIA-based, 1.0, 1.2 and 1.6 GHz C7-M processor portfolio, where the lowest speed model is optimized for running an SSD-based 4GB Linux distribution with a sub-??$ 500 price tag, while the middle tier carries Windows XP and the top model comes with Windows Vista Business, factory default. HP chose the single-core VIA C7-M CPU in order to meet the already fixed ??$ 499 starting price, even though Intel's competing Atom processor line debuted on the 2nd of April, 2008.
VIA C-7-M

Intel® Atom™ Processor N270 (512K Cache, 1.60 GHz, 533 MHz FSB)
The Intel Atom N270 broke new ground in June 2008 with a footprint 40% of a standard mobile celeron processor. Matched with the 945GSE chipset and 82801 (ICH7M) core logic.

Intel® Atom™ Processor N280 (512K Cache, 1.66 GHz, 667 MHz FSB)
The Intel Atom N280 was launched in February 2009 and sees a slight boost in computing power while decreasing its power consumption by 20%. This CPU was commonly matched with the 945GSE chipset

Intel® Atom™ Processor N450 (512K Cache, 1.66 GHz)
Thesingle-core Atom N450 chip,launched in December 2009, is 60 percent smaller than existing Atom processors, and consumes close to 20 percent less power.

The Atom N450 used in netboooks run a clock speed of 1.66GHz, just like the Atom N280 netbook chip. You may not see this as an improvement at this level but the N450 integrates the graphics and memory controller into the CPU which results in a smaler package. The N450 will process multimedia faster and free up bandwidth for the processor to communicate with other components. The N270 and N280 all have the graphics and memory controller resided outside the CPU.

The Intel® Atom™ Processor N455 (512K Cache, 1.66 GHz) appeared on our shores about three weeks ago. This processor builds on the Atom N450s capabilities by adding support for software overclocking of up to 1.88GHz. Most devices sporting this processor come with DDR3 667MHz RAM which makes it slightly faster than devices equipped with the Atom N450.

Is it enough to upgrade to devices that use this processor? Only if you are using an Atom N270 or N280.

See the comparison of both Atom N450 and Atom N455 processors here.

Both processors perform similarly and being a user of an N450 powered netbook, I'm lready impressed with what an N450 is capable of. Of course there are times when you'll need the extra power. But what are you running on your netbook anyway?

For Netbook users on the N450 this change might be insignificant, as the performance level of the unit can be increased via the Bios settings. Yes, units like the MSI Wind U160 with the latest Bios have this performance level option.

The nice thing though about the N455 powerd MSI Wind series is that they are able to take advantage of the processor's overclocking abilities without diving into the Bios settings.
